Which bone contributes to forming the orbit?

The orbit is a multi-bone cavity that forms the eye socket, with several bones contributing to its walls and margins. The frontal bone specifically forms the orbital roof and the superior boundary, making it the bone that contributes to the orbit. The other options don’t participate in forming the orbital margins in the same way: the mandible is the lower jaw and not part of the orbital bones; the parietal bones contribute to the cranial vault rather than the orbital rims; and the occipital bone forms the posterior skull and does not touch the orbit.
